Hi,
I've got planning permission through for a large extension to the tired old house I've bought. It currently has a 19 year old Potterton boiler and micro-bore pipe-work to very sluggish rads with corroded valves.
It'll be next spring before we can start the building work, which will include a new central heating system (boiler & hw cylinder) in the new utility room, as well as u/f heating & rads in the new / altered rooms. However, one side of the house remains untouched (hall / living room / master bed / bed 3). We will have to live in that part of the house during much of the work, so I want to get any intrusive work on those rooms out of the way now. We also have to make it through the winter!
So... it seemed like a good idea to me to replace the rads in those rooms, and the micro-bore with 15mm back to the 22mm "spine" that runs under the landing floor. However my plumber advised not to put new rads onto the cruddy old system, so much so that he doesn't want the job. He says do the whole system or nothing at all. He's done a couple of jobs already to try to get the existing system to limp through to next spring and he was f'ing and blinding his way through it and at one point was heard to mutter "never again" (imperial measure pipework, corroded everything, etc.) so I really can't trust if he just doesn't want the hassle, or if his "professional advise" has sound technical justification.
I'd like a 2nd (3rd, 4th, etc.) opinion from the trustworthy folk here in DIYnot please.
Thanks
James
